Overview
The Business Component Development with Enterprise JavaBeans Technology course provides students with the knowledge of how to develop robust back-end functionality using Enterprise JavaBeans (EJB) version 3.0 technology. This course uses an online auction scenario to demonstrate how to leverage container-managed services with session and message beans, and entity classes to resolve the real-world problems presented by an electronic commerce application. The emphasis of this course is on providing practical EJB technology coding experience, while also covering the designs and best practices used to solve transaction, messaging, and security issues. The course features the Java Platform, Enterprise Edition 5 (Java EE 5) technology, and uses the Java EE 5 SDK. The students perform the course lab exercises using the NetBeans Integrated Development Environment (IDE) 5.5. The hands-on lab environment uses the Java EE reference implementation server to provide students with a non-vendor-specific experience.

Objectives

Upon completion of this course, students should be able to:
· Implement business-tier functionality using EJB technology
· Describe best practices and other advanced issues in business component development with EJB technology
· Assemble and deploy EJB technology business-tier components on an application server
· Integrate an EJB technology-based application using the Java Messaging Service API
· Create and use Query objects using the Java Persistence Query Language

PreRequisites

To succeed fully in this course, students should be able to:
· Display experience with the Java programming language
· Integrate existing Java code (for example, reuse existing classes created by other team members)
· Design Java technology applications
· Although not required, experience with distributed computing concepts in Java technology is an advantage

Who Can Benefit

Students who can benefit from this course are EJB technology business component developers who are tasked with the following responsibilities: Analyzing, designing, developing, and testing EJB technology applications, Deploying an EJB technology application, Integrating an EJB technology application with a legacy application
